(a)
To design an experiment that will require a two sample t procedure to analyse the results.
(a)
Explanation of Solution
In the question agricultural researchers wants to design an experiment to find out can a food additive increase egg production. They have two kinds of feed: the regular feed and the new feed with the additive. Thus, to design an experiment that will require a two sample t procedure to analyse the results we have to randomly choose
(b)
To design an experiment that will require a matched-pairs t procedure to analyse the results.
(b)

(c)
To explain which experiment would you consider the stronger design and why.
(c)
Answer to Problem 1E
The matched pair design is considered to be stronger.
Explanation of Solution
In the question agricultural researchers wants to design an experiment to find out can a food additive increase egg production. They have two kinds of feed: the regular feed and the new feed with the additive. Thus, by looking at the two designs in the above part (a) and (b), that is to design an experiment that will require a two sample t procedure to analyse the results and second one to design an experiment that will require a matched-pairs t procedure to analyse the results, we can say that we would consider the design of the matched pairs the stronger design because the hens vary in their egg production and matched pairs will help with that.

- solve the question based on hw 1, 1.41arrow_forwardT1.4: Let ẞ(G) be the minimum size of a vertex cover, a(G) be the maximum size of an independent set and m(G) = |E(G)|. (i) Prove that if G is triangle free (no induced K3) then m(G) ≤ a(G)B(G). Hints - The neighborhood of a vertex in a triangle free graph must be independent; all edges have at least one end in a vertex cover. (ii) Show that all graphs of order n ≥ 3 and size m> [n2/4] contain a triangle. Hints - you may need to use either elementary calculus or the arithmetic-geometric mean inequality.arrow_forwardWe consider the one-period model studied in class as an example. Namely, we assumethat the current stock price is S0 = 10. At time T, the stock has either moved up toSt = 12 (with probability p = 0.6) or down towards St = 8 (with probability 1−p = 0.4).We consider a call option on this stock with maturity T and strike price K = 10. Theinterest rate on the money market is zero.As in class, we assume that you, as a customer, are willing to buy the call option on100 shares of stock for $120. The investor, who sold you the option, can adopt one of thefollowing strategies: Strategy 1: (seen in class) Buy 50 shares of stock and borrow $380. Strategy 2: Buy 55 shares of stock and borrow $430. Strategy 3: Buy 60 shares of stock and borrow $480. Strategy 4: Buy 40 shares of stock and borrow $280.(a) For each of strategies 2-4, describe the value of the investor’s portfolio at time 0,and at time T for each possible movement of the stock.(b) For each of strategies 2-4, does the investor have…arrow_forward
